What Dinex does
Dinex A/S is a Danish family-owned Tier 1 supplier of complete exhaust aftertreatment systems for heavy-duty commercial vehicles, off-road machinery, marine engines, and stationary power generation. Founded in 1982 by Jørgen and Grethe Dinesen and still controlled by the founding family (Group CEO Torben Dinesen), the company designs, develops, and manufactures the full stack of aftertreatment components in-house — including proprietary DiSiCHP silicon-carbide diesel particulate filters, DiFlex leak-tight decoupling elements, Low-PGM diesel oxidation catalysts, Cu/Fe/vanadate SCR catalysts, double-swirl mixers, integrated e-heaters, thermally insulated components, and fuel-cell membrane electrode assemblies (CCM/MEA). Global R&D and validation infrastructure spans a catalyst laboratory in Bayreuth (Germany), a Test & Validation Centre in Middelfart (Denmark) with engine dynos up to 600 kW, and engineering in Chennai (India).
The company operates a dual business model: an OEM channel that embeds Dinex systems into commercial vehicle platforms from concept through serial production under long-term supply contracts, and an aftermarket channel that distributes replacement components through 19 distribution centers. Revenue is generated via B2B hardware sales to enterprise OEM customers across on-road trucks and buses, off-road construction and agricultural equipment, and large engines (marine, rail, gensets). The OEM go-to-market combines direct field sales with embedded engineering support across regional offices in Europe, Turkey, India, China, and the United States, while the aftermarket is served through authorized resellers and regional warehouses. Pricing is quote-based and negotiated per OEM program; no public pricing or revenue figures are disclosed.
Dinex operates 7 production sites on 3 continents and employs approximately 1,800 people globally, including roughly 140 engineers and R&D staff. The company has sustained a 10%+ CAGR over 15 years, with products installed in over 1 million vehicles worldwide, and is positioning for future Euro 7, EPA 27, Tier 5, and Stage VI standards alongside emerging hydrogen combustion, ammonia, and PEM fuel cell applications.

Dinex competitors and assessment
Company assessmentBroad incumbents
- Denso: Denso is one of the world's largest automotive component suppliers with significant emissions and powertrain product lines including exhaust gas temperature sensors, oxygen sensors, and aftertreatment components. It serves many of the same global OEMs as Dinex but with a vastly broader product portfolio and deeper R&D resources.
- Continental Automotive: Continental is a major global automotive supplier with powertrain and emission control technologies including SCR dosing, sensors, and exhaust gas management systems. While broader in scope, it overlaps with Dinex in emission control electronics and aftertreatment integration for commercial vehicle OEMs.
- Faurecia (Forvia): Forvia (parent of Faurecia) is one of the world's largest automotive suppliers with a major Clean Mobility division covering exhaust aftertreatment, emissions control, and fuel cell technologies. It competes with Dinex for OEM aftertreatment sockets across commercial vehicle and passenger car platforms but operates at much larger scale and broader scope.
- Tenneco: Tenneco's Clean Air division is a global Tier 1 supplier of exhaust aftertreatment systems, emissions control products, and ride performance solutions. It serves the same heavy-duty and light-duty OEM customers as Dinex across similar regulatory standards (Euro 6/7, EPA, Tier 4/5) but at significantly larger scale and broader product portfolio.
Emerging players
- Katcon Global: Katcon is a Mexico-based Tier 1 supplier of exhaust aftertreatment systems and catalysts serving commercial vehicles, off-road, and industrial markets globally. It is a comparable peer to Dinex in product scope and OEM focus but at a smaller scale, with growing presence in North America and Europe.

- Cummins Emission Solutions: Cummins Emission Solutions is the in-house division of Cummins focused on aftertreatment systems for diesel and natural gas engines in commercial vehicles, off-road, and industrial applications. It is highly comparable to Dinex's heavy-duty and large-engine emissions business and competes directly for OEM platforms in on-road and off-road segments.
- Bosal: Bosal is a Belgian-Dutch Tier 1 supplier specializing in complete exhaust systems, catalytic converters, and tow bars for OEMs and the aftermarket. It is a closely comparable peer to Dinex in terms of product scope (exhaust systems + aftermarket), customer type (OEMs + distributors), and European heavy-duty focus.
- Donaldson Company: Donaldson is a global manufacturer of filtration systems including diesel particulate filters and exhaust aftertreatment components for heavy-duty, off-road, and industrial applications. It overlaps directly with Dinex's DPF and filtration portfolio and serves overlapping OEM and aftermarket customers.
- HJS Emission Technology: HJS is a German family-owned Tier 1 supplier specializing in exhaust aftertreatment systems, oxidation catalysts, particulate filters, and SCR technology for commercial vehicles, off-road, and stationary engines. It is highly comparable to Dinex in terms of European private ownership, product focus, and OEM customer base.
- Eberspächer: Eberspächer is a privately-held German Tier 1 specialist in exhaust technology, catalytic converters, and acoustic solutions for passenger cars and commercial vehicles. Like Dinex, it supplies complete exhaust aftertreatment systems to global OEMs and is one of Dinex's closest direct competitors in heavy-duty emission systems.
